slidewire-developer
by peterfoxBuild and refine SlideWire presentations in Laravel/Livewire applications. Use when asked to create, update, or improve slide decks, add slides, configure themes, use fragments, add code blocks or diagrams, or work with the wendelladriel/slidewire package. Triggers on requests like "create a SlideWire presentation", "add slides to...", "build a presentation with SlideWire", "write a slide deck", "add a code slide", "configure SlideWire themes", "add a Mermaid diagram", or "set up vertical navigation".
remotion-3d-background-developer
by peterfoxGenerate visually stunning, colorful, procedural 3D backgrounds for Remotion videos using react-three-fiber and GLSL shaders. Use this skill whenever a user asks for: animated backgrounds, 3D backgrounds, shader backgrounds, liquid gradients, plasma effects, aurora effects, galaxy/nebula backgrounds, noise-based patterns, or any kind of procedurally generated visual backdrop for Remotion. Also trigger when the user wants to make a Remotion video "look more interesting", "add a background", or "make it pop visually". All backgrounds are deterministic — driven by useCurrentFrame() — so they render frame-perfectly in Remotion.
phpstan-developer
by peterfoxBuild PHPStan rules, collectors, and extensions that analyze PHP code for custom errors. Use when asked to create, modify, or explain PHPStan rules, collectors, or type extensions. Triggers on requests like "write a PHPStan rule to...", "create a PHPStan rule that...", "add a PHPStan rule for...", "write a collector for...", or when working on a phpstan extension package.
php-type-safety
by peterfoxPHP type safety patterns using webmozarts/assert for runtime validation combined with PHPDoc annotations for static analysis. Use this skill whenever writing or reviewing PHP code that needs to pass PHPStan or Psalm at strict levels, when adding type assertions to method/function parameters, when typing complex array structures (shapes, maps, lists), when defining reusable type aliases, or when annotating anonymous objects and key/value arrays. Trigger on phrases like "add type assertions", "type this array properly", "make this pass PHPStan", "annotate with PHPDoc", "use webmozarts assert", "type hints for static analysis", "psalm types", or any request to improve type safety in PHP code.
laravel-advanced-concepts
by peterfoxAdvanced Laravel architectural patterns: Feature Flags, State Machines, and Event Sourcing. Use this skill whenever a user asks about: toggling features for users/groups, gradual rollouts, A/B testing, beta access (→ Feature Flags); modeling workflows like order status, subscription lifecycle, booking states, anything with defined transitions (→ State Machines); financial ledgers, credit/wallet systems, audit trails, undo history, GDPR-compliant data deletion, analytics replay (→ Event Sourcing). Also trigger when users mention spatie/laravel-model-states, Laravel Pennant, spatie/laravel-event-sourcing, hirethunk/verbs, or ask "how should I model X in Laravel" for any complex domain. This skill provides library recommendations, code patterns, and decision guidance — use it proactively whenever the user's domain sounds like it fits one of these patterns.
npm-upgrade
by peterfoxGuides Node.js project upgrades using npm, yarn, or pnpm. Use when helping users upgrade npm packages, check for security vulnerabilities with `npm audit`, prioritize which packages to upgrade first, understand dependency conflicts, interpret `npm outdated` output, use `npm explain` to trace who requires a package, plan safe upgrade paths, resolve package version conflicts in package.json, or resolve merge conflicts in package-lock.json / yarn.lock / pnpm-lock.yaml. Trigger this skill whenever the user mentions npm packages, Node.js dependencies, outdated packages, CVEs in JavaScript or TypeScript projects, yarn or pnpm upgrades, or security advisories in package.json.

Explore the agent skills ecosystem by occupation and creator
SkillMD is not just a keyword search box. It is an open map that organizes public skills by occupation, creator, and repository, helping you see which workflows, judgment criteria, and domain habits people are writing for AI agents.
Then follow creators and GitHub repositories back to the source: compare the skills a team maintains, whether the repo is active, and how the README frames the work before you open, install, or reuse anything.
Use it three ways: learn an unfamiliar field by occupation, study how creators organize skills, then use source context to decide what is worth opening or reusing.
01 Map a field
Browse 23 occupation groups and 867 SOC roles to learn what skills exist in adjacent domains and how they break down real work.
02 Follow creators
Use creator and repository pages to inspect maintained skill collections, recent updates, and source context before trusting a result.
03 Search with sources
Search 1.7M+ collected skills, then use occupation tags, creators, and GitHub source context to decide what is worth opening.
Start with the occupation map, then follow creators and repositories back to real code. SkillMD helps explain why a skill is worth opening, not only what it is named.
Standardizing Agent Capabilities with SKILL.md and Model Context Protocol (MCP)
In the rapidly evolving landscape of artificial intelligence, LLM agents (Large Language Model agents) have transitioned from simple text predictors to autonomous problem solvers. To orchestrate complex, multi-step agentic workflows, developers require a standardized format to specify agent capabilities, prompt instructions, system rules, and database bindings. This is where SKILL.md and the Model Context Protocol (MCP) have emerged as standard developer paradigms. SkillMD serves as the central directory for indexing, exploring, and sharing these critical agent configurations.
Our open-source registry currently tracks over 1.7 million collected SKILL.md configurations and system prompts. By compiling agent configurations from active developers on GitHub, we bridge the gap between prompt engineering research and production execution. Whether you are building agents with Anthropic's Claude Code, OpenAI's GPT-4, Google's Gemini, or local models using Ollama and LlamaIndex, standardized skill definitions ensure your agents behave predictably across different runtime environments.
What is the Model Context Protocol (MCP)?
The Model Context Protocol (MCP) is an open-source standard designed to connect LLMs to data sources, developer tools, and external environments. MCP establishes a bidirectional communication channel between client applications (like Cursor, Claude Desktop, or custom agent systems) and servers hosting data or capabilities. Standardizing instructions via SKILL.md enables LLMs to query databases, read local files, execute terminal commands, and integrate third-party APIs. SkillMD allows you to find ready-to-run MCP servers and prompt instructions for various occupations and technical tasks.
The Structure of a Professional SKILL.md File
A valid SKILL.md configuration is designed to be easily read by humans and parsed by LLMs. It contains precise system instructions, trigger conditions, required parameters, and execution examples. Below is the typical architectural blueprint of a professional agent skill:
- Metadata & Core Scope: Declares the name of the skill, author details, target models, and a description of the capability.
- Triggers & Intent Detection: Details semantic triggers that help the agent decide when to invoke this skill.
- System Prompts: Explicit system-level instructions that direct the agent's behavior, personality, safety guardrails, and formatting preferences.
- Capabilities & Tools: Lists the files, databases, or APIs the agent must access to complete the tasks.
- Few-Shot Examples: Demonstrates real inputs and outputs, helping the model generalize behavior through in-context learning.
Optimizing Agent Workflows for Modern LLMs
Writing effective agent skills requires deep knowledge of prompt engineering. With the release of advanced reasoning models like Claude 3.5 Sonnet, ChatGPT o1, and DeepSeek-V3, prompt templates must focus on structured thinking. Developers are encouraged to use XML tags (e.g., <thought>, <context>, and <rules>) to isolate execution boundaries. Standardized prompts prevent agents from suffering from context drift, ensuring that long-running tasks remain aligned with the initial system parameters.
Exploring by SOC Occupations and Creator Profiles
What makes SkillMD unique is its taxonomy. Instead of simple text search, we parse and organize files according to the Standard Occupational Classification (SOC) system. This means you can discover skills written for Computer and Mathematical roles, Business and Financial operations, Legal, Design, and and Educational Instruction fields. By tracking creator profiles, developers can study how different teams organize their custom instructions, compare version updates, and fork public configs for specialized enterprise use cases.
SkillMD operates as a high-performance index running on a fast Go backend and a highly responsive Astro SSR frontend. All search queries execute in milliseconds, featuring smart debouncing to prevent multiple API requests while keeping user data secure.
